Questions and Answers

What happens to the specific resistance of pure metals with an increase in temperature?

  • It increases
  • It fluctuates
  • It decreases (correct)
  • It remains constant

    • How is conductivity defined in relation to specific resistance?

  • It is unrelated to specific resistance
  • It is the reciprocal of specific resistance (correct)
  • It is the same as specific resistance
  • It is directly proportional to specific resistance

    • On what factors does the resistance of a conductor depend?

  • Length and temperature
  • Material and length
  • Cross-sectional area and length
